2x2, 5x5, and Gordians Knot

I have been saving to get some new puzzles, since the only 2 that I own currently are the original 3x3 Rubik's cube and the Sudoku Rubik's cube. I started speed solving 3x3's in May, I have gotten my time down to around a minute and a half. The sudoku cube is harder, I have only solved it twice and cant imagine speed solving it.

So last night I bribed my mom into ordering some puzzles of Amazon if I would pay her for them all I needed was the credit card. So I bought the 5x5 Professors Rubik's Cube (Holy..), A 2x2 Rubik's Ice Cube and the Gordian's Knot Puzzle. All that totaled me $70 give or take a few. Anyways they should be arriving here tomorrow and I'm pumped. The 5x5, and 2x2 i hope are self explanatory. But the Gordian's Knot puzzle, a friend in my study hall has one. It is supposedly the world's best mind teaser. I'll take that title to the test.

I'd like to know how the gordian knot puzzle goes. I've been thinking about getting some new puzzle games, as the Rubik's cube is getting old (I'm also a speed-solver; I average ~35 seconds); I don't feel like learning the Fredrich method... too much memorization.

The 5x5x5 professor's cube is just a little overwhelming, even though it looks like the 4x4x4 would be much harder.

I'm still working the Gordian's Knot, a fun puzzle for a rainy day. But the puzzle can get frustrating.. And I learned that the puzzle can be solved all to easy when a little extra force is added . I'm currently in the stage of assembling the "knot" back again to it's original state which is easier said than done.
The 2x2 is a fun little puzzle to carry around with you, If you apply a basic method of a 3x3 (fish method, cross, H method, ect.) it can be easily solved. I used a java timer and averaged around 20 sec per solve with my best at 13.42sec, I'm sure with a little practice I could have an average of under 10.
I still haven't received my 5x5 so I will keep you posted on that headache.

I think I more am into the rubik's like puzzles, so I'm thinking after I get bored with my 2x2, and 5x5 I will order a Pyraminx and maybe a Megaminx (yikes).
